Person Infected With Bird Flu in Texas After Contact With Cattle – The New York Times

Published

 on


An unusual bird flu outbreak in dairy cows has now affected at least 13 herds in six states, according to federal and state officials. These infections represent the first time that a highly pathogenic bird flu virus, which is often fatal in birds, has been detected in U.S. cattle.

At least one person in Texas has been diagnosed with bird flu after having contact with dairy cows presumed to be infected, state officials said on Monday. The patient’s primary symptom was conjunctivitis; the individual is being treated with an antiviral drug and is recovering, according to the Centers for Disease Control and Prevention.

The virus has been identified as the same version of H5N1, an influenza subtype, that is circulating in North American birds. Scientists have not found evidence that the virus has acquired the mutations it would need to spread easily between humans, officials have said.

The risk to the general public remains low, experts said. But these developments add a worrying dimension to an avian influenza outbreak that has already affected millions of birds and sea mammals worldwide.

Here’s what to know:

What is bird flu?

Bird flu, or avian influenza, is a group of flu viruses that are primarily adapted to birds. The particular virus in these new cases, called H5N1, was first identified in 1996 in geese in China, and in people in Hong Kong in 1997.

In 2020, a new, highly pathogenic form of H5N1 emerged in Europe and spread quickly around the world. In the United States, it has affected more than 82 million farmed birds, the worst bird flu outbreak in U.S. history.

Since the virus was first identified, sporadic cases have been found in people in other countries. But a vast majority resulted from prolonged, direct contact with birds.

H5N1 does not yet seem to have adapted to spread efficiently among people, experts say.

How did cows get bird flu?

Cows were not thought to be a species at high risk.

“The fact that they are susceptible — the virus can replicate, can make them sick — that is something I wouldn’t have predicted,” said Richard Webby, an influenza virologist at St. Jude Children’s Research Hospital.

But this year, reports of sick cows began to emerge in Texas and New Mexico. Dead birds were also found on some of these farms, and laboratory testing confirmed that some cows were infected with bird flu. (In Texas, three symptomatic cats also tested positive for the virus, the Texas Animal Health Commission said in an email. Feline infections are not new; cats are known to be susceptible to the virus, which they can pick up when they hunt or eat infected birds.)

It is not entirely clear how the virus found its way into cattle. But one likely route, several experts said, is that infected wild birds, which shed the virus in their feces, saliva and other secretions, contaminated the cows’ food or water.

How have cows been affected?

Although the virus is often fatal in birds, it appears to be causing relatively mild illness in cows.

“It’s not killing animals, and they seem to be recovering,” said Dr. Joe Armstrong, a veterinarian and cattle production expert at the University of Minnesota Extension. Last week, the U.S.D.A. said that there were no plans to “depopulate,” or kill, affected herds, which is the standard procedure when poultry flocks are infected with the virus.

The disease is primarily affecting older cows, which have developed symptoms that include a loss of appetite, a low-grade fever and a significant drop in milk production. The milk that the cows do produce is often “thick and discolored,” according to Texas officials. The virus has also been found in unpasteurized milk samples collected from sick cows.

It is not yet clear whether the bird flu virus is the sole cause of all the symptoms and illnesses that have been reported, experts cautioned.

How widespread is the problem?

It’s unclear. On Tuesday, the U.S.D.A. said that its National Veterinary Services Laboratories had confirmed bird flu infections in 12 herds to date: seven in Texas, two in Kansas and one each in Michigan, New Mexico and Idaho. On Wednesday, Ohio’s Department of Agriculture announced that it had also received confirmation of an affected herd from the national laboratories.

So far, the virus has been found only in dairy cows and not in beef cattle.

But because cows are not routinely tested for bird flu, and the illness has been relatively mild, there could be other infected herds that have escaped detection, experts said.

And the movement of cattle between states could transport the virus to new locations. The affected dairy in Michigan had recently imported cows from an infected herd in Texas. When the cows were transported, the animals were not displaying any symptoms. The farm in Idaho had also recently imported cows from an affected state, Idaho officials said.

How is it spreading?

That is a key, and still unanswered, question. It is possible that the infected cows are picking up the virus independently, especially if shared food or water sources have been contaminated.

A more worrisome possibility, however, is that the virus is spreading from cow to cow. On Friday, the U.S.D.A. noted that “transmission between cattle cannot be ruled out.”

Several scientists said that they would be surprised if there were not some degree of cow-to-cow transmission. “How else could it move so rapidly?” said Dr. Gregory Gray, an infectious disease epidemiologist at the University of Texas Medical Branch.

If the virus can spread easily between cows, that could lead to larger, more sustained outbreaks. It would also give the virus more opportunities to adapt to its new mammalian hosts, increasing the risk that it acquires mutations that make it more dangerous to people.

What do we know about the human case?

This is only the second case of H5N1 bird flu in people in the United States; the first was in 2022.

The patient worked directly with sick dairy cows, said Lara M. Anton, a spokeswoman for the Texas Department of State Health Services. “We have tested around a dozen symptomatic people who work at dairies, and only the one person has tested positive” for the virus, she said in an email on Monday.

A sample of virus from the patient displayed one mutation that allows it infect people more easily. But to be capable of spreading from one person to another, the virus must acquire several additional mutations — not an easy evolutionary feat.

The C.D.C. is working with state health departments to monitor other people who may have been in contact with infected birds and animals, the agency said on Monday. It also urged people to avoid exposure to sick or dead birds and animals, and to raw milk, feces or other potentially contaminated materials.

How will officials know if bird flu adapts to spread between people?

Analyzing the genetic sequence of the virus from infected birds, cows and people can reveal whether H5N1 has acquired mutations that help it spread among people.

Scientists have been closely tracking infections in birds and sea mammals and, now, cows. So far, the virus does not seem to have the ability to spread efficiently between people.

In 2012, scientists showed that H5N1 was able to spread through air between ferrets — a popular model for studying transmission of respiratory viruses among people — after acquiring five mutations.

A sample of bird flu isolated from a Chilean man last year had two mutations that indicate adaptation to infecting mammals. But those mutations have previously been seen without the virus evolving further to spread between people, experts said.

Is it safe to consume dairy products?

Federal officials have stressed that commercially processed milk remains safe to drink. Dairies are required to keep milk from sick animals out of the human food supply, and milk sold across state lines must be pasteurized, a process in which the milk is heated to kill potential pathogens. Pasteurization “has continually proven to inactivate bacteria and viruses, like influenza, in milk,” the Food and Drug Administration said in a new online guide to milk safety.

Dr. Gail Hansen, a veterinary public health expert and independent consultant, agreed that the risk was probably “very low.” She added, “I would not want people to stop drinking milk because of it.”

But the possibility could not be entirely ruled out, she said, expressing some concern that federal officials had been “overconfident in the face of so many unknowns.” If cows are shedding virus into their milk before they show signs of illness, that milk could potentially find its way into the commercial supply, she said. And different pathogens may require different pasteurization temperatures and durations; the specific conditions required to inactivate this particular virus remained unclear, Dr. Hansen said.

The risk of being infected by the virus by consuming unpasteurized, or raw, dairy products is unknown, the F.D.A. said. Raw milk is known to pose a variety of potential disease risks beyond avian influenza.

Health Canada approves updated Moderna COVID-19 vaccine

Published

 on

 

TORONTO – Health Canada has authorized Moderna’s updated COVID-19 vaccine that protects against currently circulating variants of the virus.

The mRNA vaccine, called Spikevax, has been reformulated to target the KP.2 subvariant of Omicron.

It will replace the previous version of the vaccine that was released a year ago, which targeted the XBB.1.5 subvariant of Omicron.

Health Canada recently asked provinces and territories to get rid of their older COVID-19 vaccines to ensure the most current vaccine will be used during this fall’s respiratory virus season.

Health Canada is also reviewing two other updated COVID-19 vaccines but has not yet authorized them.

They are Pfizer’s Comirnaty, which is also an mRNA vaccine, as well as Novavax’s protein-based vaccine.

These people say they got listeria after drinking recalled plant-based milks

Published

 on

 

TORONTO – Sanniah Jabeen holds a sonogram of the unborn baby she lost after contracting listeria last December. Beneath, it says “love at first sight.”

Jabeen says she believes she and her baby were poisoned by a listeria outbreak linked to some plant-based milks and wants answers. An investigation continues into the recall declared July 8 of several Silk and Great Value plant-based beverages.

“I don’t even have the words. I’m still processing that,” Jabeen says of her loss. She was 18 weeks pregnant when she went into preterm labour.

The first infection linked to the recall was traced back to August 2023. One year later on Aug. 12, 2024, the Public Health Agency of Canada said three people had died and 20 were infected.

The number of cases is likely much higher, says Lawrence Goodridge, Canada Research Chair in foodborne pathogen dynamics at the University of Guelph: “For every person known, generally speaking, there’s typically 20 to 25 or maybe 30 people that are unknown.”

The case count has remained unchanged over the last month, but the Public Health Agency of Canada says it won’t declare the outbreak over until early October because of listeria’s 70-day incubation period and the reporting delays that accompany it.

Danone Canada’s head of communications said in an email Wednesday that the company is still investigating the “root cause” of the outbreak, which has been linked to a production line at a Pickering, Ont., packaging facility.

Pregnant people, adults over 60, and those with weakened immune systems are most at risk of becoming sick with severe listeriosis. If the infection spreads to an unborn baby, Health Canada says it can cause miscarriage, stillbirth, premature birth or life-threatening illness in a newborn.

The Canadian Press spoke to 10 people, from the parents of a toddler to an 89-year-old senior, who say they became sick with listeria after drinking from cartons of plant-based milk stamped with the recalled product code. Here’s a look at some of their experiences.

Sanniah Jabeen, 32, Toronto

Jabeen says she regularly drank Silk oat and almond milk in smoothies while pregnant, and began vomiting seven times a day and shivering at night in December 2023. She had “the worst headache of (her) life” when she went to the emergency room on Dec. 15.

“I just wasn’t functioning like a normal human being,” Jabeen says.

Told she was dehydrated, Jabeen was given fluids and a blood test and sent home. Four days later, she returned to hospital.

“They told me that since you’re 18 weeks, there’s nothing you can do to save your baby,” says Jabeen, who moved to Toronto from Pakistan five years ago.

Jabeen later learned she had listeriosis and an autopsy revealed her baby was infected, too.

“It broke my heart to read that report because I was just imagining my baby drinking poisoned amniotic fluid inside of me. The womb is a place where your baby is supposed to be the safest,” Jabeen said.

Jabeen’s case is likely not included in PHAC’s count. Jabeen says she was called by Health Canada and asked what dairy and fresh produce she ate – foods more commonly associated with listeria – but not asked about plant-based beverages.

She’s pregnant again, and is due in several months. At first, she was scared to eat, not knowing what caused the infection during her last pregnancy.

“Ever since I learned about the almond, oat milk situation, I’ve been feeling a bit better knowing that it wasn’t something that I did. It was something else that caused it. It wasn’t my fault,” Jabeen said.

She’s since joined a proposed class action lawsuit launched by LPC Avocates against the manufacturers and sellers of Silk and Great Value plant-based beverages. The lawsuit has not yet been certified by a judge.

Natalie Grant and her seven year-old daughter, Bowmanville, Ont.

Natalie Grant says she was in a hospital waiting room when she saw a television news report about the recall. She wondered if the dark chocolate almond milk her daughter drank daily was contaminated.

She had brought the girl to hospital because she was vomiting every half hour, constantly on the toilet with diarrhea, and had severe pain in her abdomen.

“I’m definitely thinking that this is a pretty solid chance that she’s got listeria at this point because I knew she had all the symptoms,” Grant says of seeing the news report.

Once her daughter could hold fluids, they went home and Grant cross-checked the recalled product code – 7825 – with the one on her carton. They matched.

“I called the emerg and I said I’m pretty confident she’s been exposed,” Grant said. She was told to return to the hospital if her daughter’s symptoms worsened. An hour and a half later, her fever spiked, the vomiting returned, her face flushed and her energy plummeted.

Grant says they were sent to a hospital in Ajax, Ont. and stayed two weeks while her daughter received antibiotics four times a day until she was discharged July 23.

“Knowing that my little one was just so affected and how it affected us as a family alone, there’s a bitterness left behind,” Grant said. She’s also joined the proposed class action.

Thelma Feldman, 89, Toronto

Thelma Feldman says she regularly taught yoga to friends in her condo building before getting sickened by listeria on July 2. Now, she has a walker and her body aches. She has headaches and digestive problems.

“I’m kind of depressed,” she says.

“It’s caused me a lot of physical and emotional pain.”

Much of the early days of her illness are a blur. She knows she boarded an ambulance with profuse diarrhea on July 2 and spent five days at North York General Hospital. Afterwards, she remembers Health Canada officials entering her apartment and removing Silk almond milk from her fridge, and volunteers from a community organization giving her sponge baths.

“At my age, 89, I’m not a kid anymore and healing takes longer,” Feldman says.

“I don’t even feel like being with people. I just sit at home.”

Jasmine Jiles and three-year-old Max, Kahnawake Mohawk Territory, Que.

Jasmine Jiles says her three-year-old son Max came down with flu-like symptoms and cradled his ears in what she interpreted as a sign of pain, like the one pounding in her own head, around early July.

When Jiles heard about the recall soon after, she called Danone Canada, the plant-based milk manufacturer, to find out if their Silk coconut milk was in the contaminated batch. It was, she says.

“My son is very small, he’s very young, so I asked what we do in terms of overall monitoring and she said someone from the company would get in touch within 24 to 48 hours,” Jiles says from a First Nations reserve near Montreal.

“I never got a call back. I never got an email”

At home, her son’s fever broke after three days, but gas pains stuck with him, she says. It took a couple weeks for him to get back to normal.

“In hindsight, I should have taken him (to the hospital) but we just tried to see if we could nurse him at home because wait times are pretty extreme,” Jiles says, “and I don’t have child care at the moment.”

Joseph Desmond, 50, Sydney, N.S.

Joseph Desmond says he suffered a seizure and fell off his sofa on July 9. He went to the emergency room, where they ran an electroencephalogram (EEG) test, and then returned home. Within hours, he had a second seizure and went back to hospital.

His third seizure happened the next morning while walking to the nurse’s station.

In severe cases of listeriosis, bacteria can spread to the central nervous system and cause seizures, according to Health Canada.

“The last two months have really been a nightmare,” says Desmond, who has joined the proposed lawsuit.

When he returned home from the hospital, his daughter took a carton of Silk dark chocolate almond milk out of the fridge and asked if he had heard about the recall. By that point, Desmond says he was on his second two-litre carton after finishing the first in June.

“It was pretty scary. Terrifying. I honestly thought I was going to die.”

Cheryl McCombe, 63, Haliburton, Ont.

The morning after suffering a second episode of vomiting, feverish sweats and diarrhea in the middle of the night in early July, Cheryl McCombe scrolled through the news on her phone and came across the recall.

A few years earlier, McCombe says she started drinking plant-based milks because it seemed like a healthier choice to splash in her morning coffee. On June 30, she bought two cartons of Silk cashew almond milk.

“It was on the (recall) list. I thought, ‘Oh my God, I got listeria,’” McCombe says. She called her doctor’s office and visited an urgent care clinic hoping to get tested and confirm her suspicion, but she says, “I was basically shut down at the door.”

Public Health Ontario does not recommend listeria testing for infected individuals with mild symptoms unless they are at risk of developing severe illness, such as people who are immunocompromised, elderly, pregnant or newborn.

“No wonder they couldn’t connect the dots,” she adds, referencing that it took close to a year for public health officials to find the source of the outbreak.

“I am a woman in my 60s and sometimes these signs are of, you know, when you’re vomiting and things like that, it can be a sign in women of a bigger issue,” McCombe says. She was seeking confirmation that wasn’t the case.

Disappointed, with her stomach still feeling off, she says she decided to boost her gut health with probiotics. After a couple weeks she started to feel like herself.

But since then, McCombe says, “I’m back on Kawartha Dairy cream in my coffee.”

B.C. mayors seek ‘immediate action’ from federal government on mental health crisis

Published

 on

 

VANCOUVER – Mayors and other leaders from several British Columbia communities say the provincial and federal governments need to take “immediate action” to tackle mental health and public safety issues that have reached crisis levels.

Vancouver Mayor Ken Sim says it’s become “abundantly clear” that mental health and addiction issues and public safety have caused crises that are “gripping” Vancouver, and he and other politicians, First Nations leaders and law enforcement officials are pleading for federal and provincial help.

In a letter to Prime Minister Justin Trudeau and Premier David Eby, mayors say there are “three critical fronts” that require action including “mandatory care” for people with severe mental health and addiction issues.

The letter says senior governments also need to bring in “meaningful bail reform” for repeat offenders, and the federal government must improve policing at Metro Vancouver ports to stop illicit drugs from coming in and stolen vehicles from being exported.

Sim says the “current system” has failed British Columbians, and the number of people dealing with severe mental health and addiction issues due to lack of proper care has “reached a critical point.”

Vancouver Police Chief Adam Palmer says repeat violent offenders are too often released on bail due to a “revolving door of justice,” and a new approach is needed to deal with mentally ill people who “pose a serious and immediate danger to themselves and others.”
